Spectrum two ft ir spectrometer

The general gas chromatography-mass spectrometry profile of terpene-diallyl maleate adduct was obtained on a GC-MS system (Shimadzu GCMS-QP2010EP) equipped with Rxi-5Sil MS quartz capillary column (length 30.0 m, inner diameter 0.25 mm, film thickness 0.25 μm, injection volume 2.0 μL). The column was held at 130 °C for 0 min, and then heated to 240 °C at a rate of 8 °C/min for 5 min. Identification of the components of terpene-diallyl maleate adduct was confirmed using total ion chromatograms and the fragmentation pattern. Fourier transform infrared spectroscopy (FT-IR) analysis of the terpene maleate adduct, terpene maleate sodium salt and terpene-diallyl maleate adduct was performed on a FT-IR Spectrometer (Spectrum Two FT-IR Spectrometer, resolution: 0.5 cm⁻¹, scan: 20 times, range: 4000–500 cm⁻¹, thin film, 25 °C).
¹H NMR and ¹³C NMR analysis were conducted with Bruker nuclear magnetic resonance instrument at 600 MHz and 150 MHz respectively. CDCl₃ was used as the solvent.

Aliquots of the polymer were subjected to the ATR-FTIR analysis. The spectrum was recorded using a Spectrum Two FT-IR Spectrometer (Bruker Vertex 70–80, Billerica, MA, USA) from 400 to 4000 cm⁻¹, with a resolution of 4 cm⁻¹ and averaged over 32 scans.
